Effects of the Dive Response on Heart Rate and Pulse Amplitude
In the space below, insert a bar graph showing the heart rate and pulse amplitude during rest, 15 seconds into the dive, just before the end of the dive, and 30 seconds after the end of the dive.
Effects of Breath-holding on Heart Rate and Pulse Amplitude
In the space below, insert a bar graph showing the heart rate and pulse amplitude during rest, 15 seconds into the breath-hold, just before the end of the breath-hold, and 30 seconds after the end of the breath-hold.
Changes in Peripheral Circulation
In the space below, insert a bar graph showing the change in peripheral circulation during rest, during the dive, and during the breath-hold.
Conclusions
Answer the following questions in complete sentences.
1. Did the amplitude of your pulse beat change during a dive and/or during a breath-hold?
During the dive the amplitude increased from .0166 to .02312 at 15 seconds into dive suggesting an increase in stroke volume due to decreased heart rate. At the end of the dive the amplitude decreased to .015 and increased after the dive to .054. During the breath holding the amplitude increased at the highest heart rate at rest had the lowest amplitude. While the heart rate decreased over the breath hold the amplitude increased slightly.
2. Did your
